FAQs
What is the measuring range and accuracy of the P202/PX202 transmitter?
The standard measuring range is -50°C to +200°C (selectable: 0-100°C, -50-100°C, or customized). It utilizes a Class A Pt100 RTD sensor element, delivering a high accuracy of Class 0.5 (±0.5% FS) for precise closed-loop thermal regulation.
What output signals and power supply options are available?
We offer 2-wire 4-20mA analog output (9-30V DC power supply, power <=0.7W) and RS485 Modbus digital output (5-30V DC, power <=0.2W). Direct 3-wire Pt100 RTD output is also supported.
Is this temperature transmitter suitable for data center liquid cooling?
Yes. It is specially designed for data center CDU cooling systems, server thermal loops, and HVAC chillers. It handles pressures up to 4 MPa and works reliably with deionized water, ethylene glycol, propylene glycol, and fluorinated liquids.
What is the difference between P202 and PX202?
P202 is a compact integrated temperature transmitter without display, ideal for tight cabinet spaces. PX202 includes an integrated 4-digit digital LED display head for on-site monitoring. Both models share identical measurement performance and IP65 protection.
What process connections and probe sizes can be customized?
We offer threaded connections (M20*1.5, G1/2, G1/4, NPT1/2, M27*2, M14*1.5) and sanitary Tri-clamp fittings (1.5", 2"). Probe diameters range from 4mm to 16mm, and insertion lengths range from 30mm to 500mm in 304SS or 316LSS.
